Activate Your Windows 10 License via Microsoft Chat Support

If you’re transferring a Windows 10 license to a new computer or need to reactivate your Windows key, here’s my experience using Microsoft Chat Support.

Microsoft still includes product activation in Windows 10 to prevent piracy. Windows 10 includes a new convenient chat option for product activation. If you upgrade from an activated Windows 7 or from Windows 8.1, Windows 10 will automatically activate. If you’re transferring a Windows 10 license to a new computer and have an Internet connection, you can use chat support to activate it.

Activate Windows 10 Using Chat Support

After installing Windows 10, press Windows key + R, then type: slui and hit Enter on your keyboard.

This action will launch the activation wizard. Select your country or region and click Next.

Then, you will be prompted to call the number listed on the screen at the Installation ID screen. If you have an active Internet connection, you can use the new chat option.

Click the Start button and head to All Apps > Contact Support.

Start Contact Support

Update: In the Windows 10 Creators Update and later versions, contacting support is now available in a new app called Get Help or you can use web browser to contact support using the virtual assistant.

You can also start chat support using your web browser. Head on over to the Microsoft Contact Us web page, then click the Get started button.

Type test in the chat window, then press Enter. Click No when prompted for a response.

Click No again, then click talk to a person.

After the call agent greets you, explain your issue. For this particular case, I want to reactivate Windows 10. You might be asked to provide your Windows 10 product key.

If you are reactivating a Windows 10 license, make sure to clarify to the agent you want a license reactivated. Provide the Installation ID generated earlier in the activation wizard. Once your Installation ID is verified, you will be given your Confirmation ID.

Proceed to enter the Confirmation ID, then click Activate Windows. And you should be good to go!

You can let the agent know the issue is resolved, then close the chat window.

Chat support can also be used to address and resolve other issues you might be experiencing in Windows 10. I was skeptical about using this, but the experience was a pleasant surprise.

    I used the live chat service when I had problems with email on Office 2010 after installing Windows 10. I was also pleasantly surprised. The operator spent about 30 mins with me and resolved my problem.

    Please help me with the following:
    When I go to Start, then Settings> Update and Security> Activation
    under the heading Activation of Windows appears to me the following
    License for Windows expire July 27, 2016, year. To obtain a product key, contact your system administrator. Error code 0xC004F074
    I do not understand what it was, so I ask for help

    After that, I got an answer and entered the following key products
    Enter the correct product key based on the edition of Windows 10 you have installed:
    Win 10 Pro: VK7JG-NPHTM-C97JM-9MPGT-3V66T

    According to the key you sent me the following occurs:
    Activation failed because the device does not contain digital rights is not a product key.
    Error code 0x803F7001

    On the computer I 29.1.2016. changed the motherboard, so I think that’s the main reason why we Windows10 is not active

    We kindly ask for help in order to activate Windows 10

    Thanks in advance

    Please edit the article to discuss what to do when “slui 4” won’t open the phone activation option and instead says “Cannot Activate Windows By Phone.”

    I am totally lost. Downloaded windows 10 …or tried to … just b4 the deadline on two devices. They chugged along for hours then crashed and reverted back to 8.1.
    How do I fix this. Is Windows 10 worth the aggravation? Is the
    Is just another Vista?

  7. Nancy McKereghan

    I had Windows 10 scheduled to download on July 29 and install but nothing happened.

    After I set the scheduler I kept getting pop-ups asking if I wanted to install earlier. Could this have something to do with why the installation didn’t occur as scheduled?

  8. Jonas

    I’m trying but “slui.exe 4” does nothing. They removed this option in the AU?

  9. Ramit Shukla

    For some reason, Slui.exe 4 doesn’t open anything. Is there any other way to do this?

  10. Jonas Schumacher

    I had to contact the support,they connected via remote assistance and solved the activation issue.

    I’m the OP. Following up on Andre’s reply:

    The slui.exe 4 command took me to a page that says “Can’t activate windows by phone. Contact your system administrator.” This is entirely consistent with my computer running under a version of windows that’s linked to the manufacturers KMS.

    I called the 1-800 number that’s shown in the screens above, and was connected to a live person. She completely ignored my explanation about the KMS, and instead probed around and told me my computer was broken. It would cost $149 to fix!

    I can get a new licensed copy of windows 10 for less than that. I can also load Linux for free.

    For now, I’m just going to see what happens when the license does expire. I gather windows will still work, but with a permanent nag watermark. Remains to be seen how annoying that is.

  13. Andre Da Costa

    If you are having problems with entering the command, try: SLUI 4 then hit Enter.

  14. Robert Nitzel

    I had the same issue, slui.exe 4, showed a screen saying can’t activate.

    Ran slui.exe, which allowed me to enter my license key.

    Then I ran slui.exe 4, and it worked, giving me my installation ID.

    Hope this helps.

  15. Kianoosh

    Thanks a lot

  17. Terry Lawson

    Reinstall windows 10 home now it is saying Activation unable to reach windows activation server. tried the SLUI 4 it will not open.


    how can know my product key coz i need to activate my windows in my laptop

  19. Richard

    Same as above – I have just installed a new motherboard. Before doing so I set up my account etc as per the instructions while I was still using the old motherboard.
    I’ve come to reactivate Windows 10, signed into the account, and now getting “We can’t reactivate Windows because our servers aren’t available right now”. They haven’t been available for a while now!
    And SLUI doesn’t work – it just goes straight to telling me to enter the serial number which, of course I don’t have, as I upgraded free from Windows 7.
    Please help!

  22. Pandu

    Thank You, im struggling before, i have full windows 10 pro license and used it on my mac bootcamp, later i buy new laptop for windows and erased the old bootcamp. When i tried to inserted the license on my new laptop it say that the license cannot be verified. Lot of ways i tried from the internet, but the simply one is worked, by using Window virtual agent on my windows 10, i just follow the instruction and the problem was solved.

    Thanks once again !

  23. William Stucke

    When I call the numbers given by SLUI, one of two things happens:
    1. The call is disconnected immediately, or,
    2. Someone tries to sell me medical insurance!

    What gives?
